Shrub rose plant named &#39;poulcot003&#39;

ABSTRACT

A new garden rose plant of the shrub rose class which has abundant, deep pink flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

BOTANICAL CLASSIFICATION

Rosa hybrid

VARIETY DENOMINATION

‘Poulcot003’

The present invention constitutes a new and distinct variety of gardenrose plant that originated from a controlled crossing between the femaleseed parent ‘Kormixal’, a non-patented variety, and the male pollenparent, an unnamed seedling.

The two parents were crossed during the summer of 1995, and theresulting seeds were planted in a controlled environment in Fredensborg,Denmark. The new variety is named ‘Poulcot003’.

The new variety may be distinguished from the female seed parent‘Kormixal’ by a difference in flower petal color. ‘Kormixal’ has mediumred flowers. ‘Poulcot003’ has deep pink flowers.

The new variety may be distinguished from its male pollen parent, anunnamed seedling, by the following combination of characteristics:

-   -   1. The male pollen parent has a flower diameter of 40 to 45 mm.        ‘Poulcot003’ has a flower diameter of 53 mm on average.    -   2. The male pollen parent has fewer thorns than ‘Poulcot003’.    -   3. The male pollen parent has light pink flowers, while        ‘Poulcot003’ has deep pink flowers.

The objective of the hybridization of this rose variety was to create anew and distinct variety for garden use with unique qualities, such as:

-   -   1. Uniform and abundant deep pink single petal flowers;    -   2. Vigorous, but compact spreading growth;    -   3. Propagates easily from soft wood cuttings;    -   4. Exhibits a profusion of rose hips;    -   3. Exceptional disease resistance.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventors, anddistinguish ‘Poulcot003’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization during winter of 1995 andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark.

‘Poulcot003’ was selected in the spring of 1996 by the inventor as asingle plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulcot003’ by traditional budding and rootedcuttings was first done by Mogens N. Olesen in the nursery inFredensborg, Denmark in July 1996. This initial and other subsequentasexual propagations conducted in controlled environments havedemonstrated that the characteristics of ‘Poulcot003’ are true to typeand are transmitted from one generation to the next.
